I have a 32" Sony Wega and all of the sudden, I cant change the channel, it keeps cycling through all of the channels and the volume adjustment runs to loudest and stays there. If I hold the button to reduce the volume it will run back down. As soon as I let go of it it runs right back up to full volume. It seems like the remote no longer communicates with the TV. I'm hoping someone can help so that I don't have to place a service call.
